When I was in junior high school, I could consider "three-year simulated five-year senior high school entrance examination", but I personally think it's a bit too much = =, and most of the questions in it have detailed answers. Personally, I just skip what I can do and try to solve the problem ... We all issue "intensive homework", that's all, it's not a big amount. I listened to "Make a mountain out of a molehill" before the middle school entrance examination, but I didn't buy it. I just tried to pick as many questions as possible.
